To all whom, it may concern/:

Be it known that I, HERMANN LEMP, a citizen of the United States, residing at Lynn,

county of Essex, State of Massachusetts, have invented certain new and useful lImprovementsin Supports for Motors for Self-Bro pelled Vehicles, (CaseNo. 2,420,) of which the following is a specification.

In connection with self-propelled vehicles it is important that the motors be suspended in such a manner that the various operating` parts are readily accessible, so that incase of repair they may be vremoved without taking the motor as a whole from the vehicle.V

The object' of thel present invention is Vto provide a motor suspension which is simple in construction, permits of the necessary adjustment of the motor as a Whole, and enables the working parts to be removed Without disturbing the stationary frame or changing its position relative to the driving-shaft or axle.

The scope of my invention will be more fully set forth in the description and in the claims appended thereto.

In the accompanying drawings, which illustrate an embodiment of my invention, Figure 1 is a side elevation of a vehicle-frame. Fig. 2 is a plan view thereof. Fig. 3 is a detail enlarged view, partially in section, of the motor viewed from the end opposite the crank and also of the means employed for supporting the same from the vehicle-fratrie. Fig. 4 is an enlarged detail View of the'hanger as viewed from the crank end ofthe motor. Fig.'

5 is a side elevation ofthe motor and the'su pports therefor. Fig. isa detail view of the outer supporting .member or ring. Figs. 7 and S are respectively a front and side elevation of the inner supporting member. Fig. 9 is an enlarged sectional view ot the hanger employed to support the transversely-extending frame-bars. Fig. 10 is a longitudinal section of the engine. Fig. 11 is a section taken on line 11 l1 of Fig. 10, and Fig. 12/is a section taken on line 12 12 of Fig. 10.

In the drawings, l represents a rectangular vehicle-frame, preferably made of Wood, and is supported from thefront axle by meansof half-elliptic springs 2 and from the'rearkaxle by full-elliptic springs 3. Extending across the frame are two parallel tubes or rods 4t and` `5, vwhich are supportedat the ends by hangers 6 and 7. x The rods are employed to'support the motors, which in the present instance take the form of engines, as will appear hereinafter. The hangers are held in placeby bolts that extend vertically through the side bars of the frame. Each hanger consists of a flat plate 8,V Fig. 9, which rests on the upper surface of'the Wooden frame-bar, and aplate 6o sockets 'are the transversely-extendingtubes 7e Vwhich-support the motors. In the end of each tube is a plug l1, which is retained in place by a pin 12. The tube is held in the socket by a bolt 13, the latter entering `the plug'll. The transversely-extending tubes 75 being supported at the ends in hangers and 7 (the latter being rigidly secured to the frame-bars) act as a 'brace for the center portion of the frame in addition to supporting the motors. Y 8o In the present. instance the motor consists. ,i of a three-cylinder single-acting engine, al though the particular form of motive device mayy be varied as desired. The cylinders are displaced by one hundred and twenty'def` 85 grees, andV one of the cylinders extends upward vertically between the frame-bars 4 and 5. The engine is provided with a front de-y tachable head 14, carrying the bearing for the crank-shaft, and is secured to the main frame 9o by bolts 15. Between the detachable head and the main frame is a supporting meansll, n made in the form of a ring of the character illustrated in Fig. 6. The ring is provided` with a shouldered portion 17, as indicated'in 95:. y

dotted lines, Fig. 6and in full 1ines'inthev sectional view Fig. 10. This shoulderedpor-- tion engages with a seat formed in tlie main engine-casing andtakes the strain olii' of the.

retaining screwsrand also oft' of the bolts Ioo t which clamp'the head-'to Vthe Vframe.` -The l ring as a whole is securedto the engine-frame by screws 18, Fig. 10, so that the engine will be supported when the head 14 and its retaining-bolts are removed. Since the bolts for securing the head to the engine-frame also pass through the ring, an additional means is provided for holding the parts together, which is important where the parts are subjected at times, asin the present instance, to great strain. The ring is provided with a pair of split bosses 19, located on opposite sides, which bosses are adapted to receive the parallel and transversely-extending frametubes and support the engine. After the engine is mounted in the proper position each boss is firmly clamped to the tube by the bolt 20, which passes through ears formed thereon. To maintain a fixed distance between the rear driving-axle 31 and the engine or crank shaft 2l for the purpose of keeping the gears in proper adjustment or the tension on the chain a fixture, it is necessary to provide a connecting device. Such a device is found in the connecting-rod 22, which is pivotally secured to the rear axle by a pivotal connection 23 and to the engine-frame by a pivotal connection 24. The last-mentioned connection consists of a fork which surrounds the lug 25, Fig. 6, ou the supporting-ring on two sides, and extending through the fork and the lug is a boltrfor holding the parts together. This arrangement permits the vehicle-frame as a whole to move up and down Without altering the tension of the sprocket-chain 26. The chain extends between a sprocket-wheel 27 on the rear wheel and a sprocket 2S on the main shaft of the engine. inasmuch as certain of the engines will be used on the lefthand side and certain of the others on the right-hand side of the frame, the pattern for the ring or supporting means 16 is provided with two lugs 25. In Fig. 6 one of these lugs is shown in full lines, While the other is shown in dotted lines, thus indicating that the one not in use has been cutoff. If desired, both of these lugs may be left on the finished part, as indicated in Fig. 1. As the shoulder `17 on the ring is made in finishing the ring, it does not have to be considered in the pattern or casting other than to providev sufficient stock.

As it is only necessary to remove one head, and that the front one, for the purpose of inspection or repair, the rear head, or one back of the crank-shaft, is provided With split bosses 29, Figs. 7 and S, which surround the parallel frame-tubes 4 and 5. If it be deemed advisable, the rear of the engine may also be provided with a ring-like support of the character illustrated in Fig. 6, in which case the split bosses would be omitted from the rear head. The head is secured to the tubes 4 and 5 by bolts 30, which pass through ears formed on the split bosses. The rear head is shown in elevation in Fig. 7, and the center thereof is bored out at 32 to receive the shaft 33, the latter being employed to adjust the cut-off cams controlling the admission "of steam to the cylinders. The head is secured to the engine-frame by bolts 84.

Each motor is entirely supported by the two transversely-extending tubes or rods 4 and 5, and the latter are supported by the end hangers 6 and 7. It will be seen that by this construction the motors as a whole may be shifted toward or away from each other in order to laterally adjust the position of the driving-sprocket 2S with respect to the rear sprocket 27. The tension on the chain can be adj usted by the connecting-rod 22.

Referring to Fig. 10, the advantages of the novel construction described Will be apparent. 1 represents the wooden frame-piece, and 7 the hanger mounted thereon for supporting the transversely-extendin g tubes. The front of the engine is supported by the shouldered ring 16 and the rear by the rear head. 40 represents the cylinders, and 41 the pistons moving therein, the latter being connected to the crank in a suitable ma nner. In the present instance roller-bearings 42 are employed to reduce the friction. The crank-pin is perfectly straight, so that it may be moved longitudinally into and out of the bearing for the purposes of assembling or removing the arts. The end of the crank-shaft is elongated at 43 to drive the cam 44. The latter is rigidly mounted on the shaft 33, and as it moves to and fro the period of steam admission is varied.

Surrounding the crank-shaft 21 and retained in place by the crank-arm on the inner end and by the disk 45 on the outer end is a sleeve 46. The sleeve is provided with a bearing 46. This arrangement is a desirable one, for when the parts are worn a newr sleeve and bearing may be inserted in place at a small cost, Whereas the cost of a new crank would be considerable. The bearing is slotted in the under side to receive a piece of felt or similar' material 47 to insure proper lubrication. The upper part of the bearing is provided with two ribs 4S, Which with the end flanges of the bearing form an oil-well. Oil or other lubricant is admitted through the covered opening 49 and feeds by gravity through the holes 50 into the oil-groove in the bearing. The crank-shaft with its extension 43 and the bearing 46 are removable with the head, so that the working parts can be taken from or returned to the engine by a single operation.

Assume, for example, that it is desired to inspect the interior of the motor for the purpose of repair or otherwise. The chain 26 is detached and the nuts removed from the bolts 15, after which the head 14, crank-shaft 21, and driving-sprocket 28 may be removed Without in any Way interfering with the motor adj ustment or suspension. Since the connecting-rod 22 is secured to the ring 16, which in turn is secured to the frame and to the rear axle,the parts may be returned to place without in any Way altering the adjustment. If it is necessary to shift the engine laterally in order to bring the driving and the driven sprockets IOO IIO

-or away from the frame-bar, as'desired.

into the same vertical plane, the bolts pass,- ing through the split'bosses are loosened andl the engine as a whole shifted either toward In Fig. 5 the engine is shown as being in the extreme left-hand position and the bosses are in engagement with the sockets 10.V I have shown two motors on the vehicle, as this arrangement possesses certain features of advantage; but I may use one motor and support it in the manner described either at one side'or at a pointoetween the side bars of the frame. With one motor the usual driving connection would be employed.

What I claim as new, and desire to secure by Letters Patent of the United States, is-
